The Edutige ETG-003 TRS to TRRS microphone adapter lets your TRS microphones be used with TRRS devices that have a TRRS audio/mic jack, like your smartphones and tablets.

That means your ETM series microphone can now work with a bunch of new devices. The ETM series microphones are a TRS microphone that will not directly work with the TRRS devices. Thanks to the ETG-003, you can now connect an ETM series microphone to your iPhone, any other iOS devices, or other popular smartphones and tablets.
